1 Claim. (Cl. 164--84.5)

The invention relates to new and useful improvements in a tapedispensing device and more particularly a tape dispensing device fortape holders of a spool type.

An object of the invention is to provide a spool tape holder with a tapedispensing device wherein the tape when ready for severing is laid overa plate and is clamped thereagainst by a cutting blade to facilitate thesevering of the tape by a pull thereon across the blade.

Another object of the invention is to provide a tape dispensing deviceof the above type wherein the plate against which the tape end ispressed for severing may be swung from between the flanges of the spoolso that the tape is made readily accessible for the next strippingoperation.

A still further object of the invention is to provide a supportingmember for the cutting blade with the means for preventing the retainedend portion of the severed tape from sticking to said blade supportingmember.

In the drawings which show by way of illustration one embodiment of theinvention:

Figure 1 is a vertical sectional view taken between the flanges of aspool tape holder with the improved dispensing device applied theretoand also shown in section;

Figure 2 is a sectional view on the line 2, 2 of Figure 1;

Figure 3 is a sectional view on the line 3, 3 of Figure 1;

Figure 4 is a view showing the dispensing device in top plan.

In my copending application, Ser. No. 367,440, filed July 13, 1953 wehave shown a tape dispensing device for a tape roll wherein the endportion of the tape which has been stripped from the roll is laid over asupporting plate and clamped thereto by a cutting blade to facilitatethe severing of the tape by a pull thereon across the blade. The presentinvention has to do with a tape dispensing device for a spool type ofholder wherein the dispensing tape is clamped for severing in the samemanner as in my copending application. Referring in detail to thepresent illustrated embodiment of the invention the dispensing device isshown as applied to a tape holder of the spool type which includes acentral supporting member or hub 1 preferably of metal. Radiallyextending outwardly over the ends of this supporting member are spacedflanges 2, 2. The supporting member is provided with outwardly extendingribs 3, 3 against which the flanges 2, 2 abut and the extreme outer ends4, 4 of the supporting member 1 are turned outwardly so as to clamp theflanges between the rib and this outwardly turned member. The flangesare rolled outwardly at their peripheral edge into a hollow reenforcingbead indicated at 5, 5. The tape with the adhesive on its inner face iswound spirally on a fiber sleeve 6 and this fiber sleeve 6, togetherwith the tape roll loosely fits on the supporting member 1 so that thetape roll can rotate on this supporting member when the tape is beingstripped from the periphery of the'roll. This tape holder referred to asspool type is very well known in the art and further description thereofis not thought necessary.

Applicants dispensing device is attached to the flanges of the spoolholder. A rod 7 extends across the spool holder parallel with the axisof the tape roll and adjacent the outer peripheral edge of the flanges2, 2. The ends of the rod are headed so as to retain it in the flanges.Mounted on this rod is a tape supporting plate 8. The rear end of thisplate 8 is bent around the rod so that it can pivot on the rod and swingoutwardly from between the flanges. There is a second rod 9 parallelwith the first rod 7 which extends through the flanges and is likewiseheaded so as to be retained in the flanges of the spool. The supportingplate 8 is of a length so that it overlies the rod 9 and is supported bysaid rod during the severing ofthe tatpe. The tape indicated at T in thedrawings is led around the plate 8 and when it is desired to dispense alength of tape it is pulled on in the general direction of the plate andthis will lay the tape over the plate 8 which serves as a supporttherefor during severing. The severing blade 10 is formed integral withthe plate 11 having depending lugs 12, 12 at the rear end of the platewhich lugs are perforated for pivoting and the rod 7 passes throughthese perforations in the lugs. This plate supporting the blade 10 isfree to pivot on the rod 7. When the desired length of tape has beendrawn from the tape roll then the plate 11 is moved in a clockwisedirection so as to bring the blade 10 into engagement with the tape andpress the tape against the supporting plate 8 therefor. While the tapeis thus clamped tightly against the supporting plate by the blade 10then the tape is drawn across the holding edge of the blade and thussevered.

After the tape has been severed and when it is desired to pull off a newlength of tape the supporting plate 8 will be swung outwardly frombetween the flanges at its free end thus carrying the plate 11 and theblade 10 together with the severed end portion of the tape free of theflanges so that the plate and blade may be separated and the tapereadily grasped for drawing off a new length.

The plate 11 is provided with slits forming a tongue 13 which is bentdownward into the space beneath the blade supporting plate 11 so as toprevent the tape from contacting the plate 11 and adhering thereto. Theblade 10 has a serrated edge 14 which aids in the cutting and rupturingof the tape for severing the drawn off end from the body portion of thetape. When the tape is severed it will cling to this serrated edge.However, if it should be freed from the serrated edge the upper sidewhich is the adhesive side will not contact the plate 11 and stickthereto.

From the above it is noted that the supporting plate 8 performs twofunctions. It serves as a means for supporting the tape for easysevering and it also serves as a means for lifting the plate supportingthe severing blade so as to position the tape end for easy access.During the stripping of the tape the tape roll together with the fibersleeve 6 will rotate freely on the supporting hub member 1 of the spool.

It is obvious that minor changes may be made in the details ofconstruction without departing from the spirit of the invention as setforth in the appended claim.

I claim:

In a spool holder for tape having a hub on which the tape roll ismounted for rotation and flanges extending radially from the hub, thecombination of a rod mounted in said flanges and extending across theholder and spaced radially outwardly from the tape roll, a supportingplate pivotally mounted on said rod over which the tape is drawn, meanscarried by the flanges on which said plate rests, a blade supportingplate pivotally mounted on said rod and a blade carried by said lastnamed plate and adapted to clamp the tape against the tape supportingplate during the severing of the tape, said blade supporting platehaving a tongue depending therefrom to prevent the tape end fromcontacting and sticking to said plate.
